To create a collection of users
Simply call the factory like this: 3.times { Factory(:user) }
To create a collection for the "many" in a has_many
Do it in FG's after_create on the belonging object. So if you wanted a test with a Company with 3 Users: Factory.define :company_with_three_users do |blog|
company.after_create do |belonging|
3.times { Factory(:user, :company => belonging) }
end
end
To create records that share parameters
Write a helper method: # in test/factories.rb or spec/factories.rb
def two_companies_for(user = Factory(:user))
[Factory(:company), Factory(:company)]
end
To connect cucumber steps for dynamic factories
Parse the cucumber step then send the match as a parameter: Given /^typical (\w+)/ do |name|
Factory(name)
end
To do more advanced expert setup with callbacks
